This visualization is a world population density map where each country is colored according to its inhabitants per square kilometer, using a sequential color scale from light blue (sparse) to red (dense). It displays a legend and tooltips on hover, allowing users to inspect individual countries. Built with D3 v7, the map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render geographic boundaries from TopoJSON data, while population statistics are parsed from a TSV file and aggregated with `d3.rollup` and `d3.sum`.

Map

A world choropleth map visualizes population by country using a blue threshold color scale. The SVG rendering combines world-atlas TopoJSON geographic features with population data from a local JSON file, linked by country ID. D3's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` draw the map and grid lines, while hover tooltips reveal country names and formatted population values.

TopoJSON

This world map choropleth visualizes population density per km² by country, using a threshold color scale with breakpoints at 1, 10, 30, 50, and 100 people per square kilometer. Countries without matching data appear gray. The visualization renders with d3.geoPath and a Mercator projection fitted to a 960×520 SVG,

map

This visualization displays a world map where each country is colored according to its population using a sequential yellow-orange-red color scale. Population data is loaded from a CSV file and merged with country geometries from the world-atlas TopoJSON dataset. The map uses a Mercator projection via d3.geoMercator and renders paths with d3.geoPath, while hovering over a country reveals its name and population in a tooltip. Missing data appears gray, and the SVG canvas includes a light blue background.

MAP

This map visualizes global population estimates for each country using a choropleth color scale, where darker reds indicate higher population values. The geographic outlines are rendered as SVG paths generated from world-atlas TopoJSON data, projected with `d3.geoMercator`. Population figures come from a TSV dataset loaded via `d3.tsv`, and the fill color is computed with `d3.scaleLinear`. The visualization also includes interactive pan and zoom functionality through `d3.zoom`, and hover states change country colors to purple via CSS.

Maps

This choropleth map visualizes world population by country using a blue sequential color scale. It loads GeoJSON country boundaries and a CSV of population data, joining them by ISO3 country codes. The map is rendered with D3.js, using `d3.geoNaturalEarth1` projection and `d3.geoPath` to draw SVG paths. Countries with missing data are shown in gray. Hovering over a country reveals a tooltip with the country name and formatted population. A gradient legend displays low-to-high population values with tick marks.

World Map Visualization

This visualization presents a choropleth world map showing population counts by country, using a blue sequential color scale on an SVG-rendered Natural Earth projection. The code loads CSV population data and GeoJSON country boundaries, then applies d3.geoNaturalEarth1 and d3.geoPath to draw each nation. Countries without matching data appear in black. Population values are converted to numbers and mapped through d3.scaleQuantize with d3.schemeBlues[5] to encode magnitude visually across the geographic layout.

This choropleth shows world population by country using a natural Earth projection. It renders country boundaries as SVG paths via d3.geoPath, with fill colors derived from a sequential YlGnBu scale encoding population values from a small embedded dataset. Hovering triggers a tooltip displaying country name and population. A gradient legend with an axis communicates the color-to-value mapping, while nations lacking data appear gray. The map loads country geometries from the world-atlas TopoJSON file, processed with topojson.feature.

Map exemple

This interactive choropleth displays global population estimates, with each country filled by a color scale ranging from light red to dark red according to its population. Built with D3 v5, the map uses TopoJSON to convert world-atlas GeoJSON features into SVG paths via a Mercator projection, while an accompanying TSV file supplies the population attributes. The visualization supports zooming and panning, and countries turn purple on hover.
